We all go through phases of having favorite foods, but for one 17-year-old British girl, it's gotten a bit out of hand -- the teen has eaten almost nothing but McDonald's chicken nuggets and french fries for the past 15 years.

Stacey Irvine's strange food habits were discovered when she collapsed and was hospitalized with breathing trouble. Doctors are currently treating her for anemia and vitamin deficiencies.

She says she's never had a single fruit or vegetable, but even though she's slowly beginning to understand her daily diet of fast food isn't good for her, she doesn't think she'll be able to stop.

Remarkably, even if her overall heath is a mess, her weight is still in check.

Her mother, Evonne, says the trouble started when she took Stacey to a McDonald's when she was 2 years old. The girl fell in love with Chicken McNuggets and thereafter refused to eat anything else.

Evonne's trying to get her daughter seen by a specialist and said, "It breaks my heart to see her eating those damned nuggets. She's been told in no uncertain terms that she'll die if she carries on like this. But she says she can't eat anything else."
